The Development of Frontal and Sphenoid Sinuses After Full-House Endoscopic Sinus Surgery in a Child.

Although endoscopic sinus surgery (ESS) is a standard procedure for adults and is considered a safe and effective procedure in children as well, some uncertainty remains when it comes to children, especially with regard to the future facial and sinus development. Overall, limited ESS does not affect sinus development, and extended ESS does not affect facial features. However, whether or not full-house ESS affects the sinus development, especially the frontal and sphenoid sinuses, remains unclear. The authors herein report a 15-year-old child who received full-house ESS and later re-examined the paranasal sinuses at 24 years old, at which point the frontal and sphenoid sinuses had developed. This is the first report showing the development of the frontal and sphenoid sinuses after such a procedure.
